Nazis were one of the worst regimes we had in Europe, but the German regime before them was also bad. Bad enough that many saw Nazis as a viable alternative. In desperate times, people make desperate choices.
This is more or less a historical consensus, which I pointed out. If we want to prevent a Nazi-like regime from coming to power again, we need to avoid mistakes made by the Weimar Republic. Unfortunately, I see a global trend of governments making the same mistakes again, and I fear it will end in the same way.
I don't think Nazi society was high-trust. But I also don't think Nazis destroyed trust, because it already eroded before them.
